Question 1

What average current must be maintained to electroplate 6.5 g of chromium per hour from a solution of chromium(III) complex?
◦ 3.4 A
◦ 6.9 A
◦ 10 A
◦ 12 A
◦ 15 A

Question 2

What is the approximate pH of the H⁺(aq)/H₂(g) electrode compartment through which H₂ gas is bubbled at a pressure of 1.00 atm if this electrode, when coupled with a Ni(s)/(0.10 M) Ni²⁺(aq) electrode, forms a galvanic cell having an initial potential of 0.10 V? [The discharge reaction involves oxidation of nickel to Ni²⁺(aq).]
◦ 2.15
◦ 4.65
